You will have to calibrate _everything_ in the path, and of course that includes the signal processing in the FPGA as well as anything in the host-based signal processing path. And yes, pretty much all of this varies depending on a large variety of settings. E.g., you'd want to calibrate for each possible FPGA decimation rate that you're interested in.
As long as you stick to power of 2 decimation, you don't need to calibrate for different settings.
